Update 3g Three Review – Operators around the world are shutting down their 2G and 3G networks. Here’s how to make sure your business is ready.
Billions of IoT devices rely on 2G and 3G cellular networks. These solutions offer IoT manufacturers an affordable way to keep devices connected from anywhere in the world—indoors, outdoors, or on the go. But the technology is decades old, there are better solutions available, and there is so much bandwidth to use. And so over the next few years, these networks are closing down for good. Why are operators shutting down their 2G and 3G networks? How should IoT businesses prepare for the sunset? When does sunset occur? Some carriers have already discontinued their 2G and 3G networks, pulling the plug to make way for newer cellular networks like 4G and 5G. Most other operators have at least planned to shut them down. Fortunately, they’ve made these plans public, so you won’t be caught off guard. In this article, we’ll share when 2G and 3G networks are shutting down around the world and what your business can do to prepare. But first, let’s see why this happens. 1. Why do operators shut down their 2G and 3G networks? Haven’t cellular operators heard the phrase “If it ain’t broke, don’t fix it”? 2G and 3G networks work well for most IoT applications. So why don’t cellular providers keep them around? It all comes down to supply and demand. 2G and 3G technologies have already gone through extensive updates to extend their lives and get the last use out of their infrastructure. But each operator has a limited range of radio frequencies that it can dedicate to its networks. And the demand for 4G, 5G, LTE-M and NB-IoT will only grow in the coming years. Most GSM-based 2G networks use the 850–1800 MHz or 900–1900 MHz frequency bands. And 3G networks use bands between 850-1900 MHz or 900-2100 MHz. More advanced cellular technologies can use these same bands to provide higher data throughput and more valuable functionality. And around the world, the opportunity these new networks offer is driving demand to continue supporting 2G and 3G infrastructure. With this in mind, it is critical that IoT manufacturers know when sunset is coming and what they need to do before then. 2. How should IoT businesses prepare for the sunset? The last thing you want is to be using a 2G or 3G network when the carrier you rely on shuts down their network. Even if you still have years on your current carrier plan, you want to be proactive, not reactive. Here’s how to make sure you’re prepared. Assess Your Current IoT Devices Some of your devices may rely entirely on 2G or 3G connectivity. Others may use it as a fallback option when other options such as 4G or LTE-M are not available. You need to take inventory of every device that relies on this technology, assess which deployments and customers will need to transition, and identify the specific carriers that use your devices. You can only change your cellular service to a new technology that your devices are already compatible with. Or disable the functionality that searches for 2G and 3G networks. In many cases, however, your devices may require a significant upgrade to continue working. Know the dates that affect your deployment Some operators will continue to support their 2G and 3G services for years. Some will transition immediately and discontinue their full service at a specific date, while others will phase out their 2G/3G service gradually while converting available spectrum to other services. You don’t need to know what each operator does. But you need to learn everything you can about how your business will depend on handling the transition. Create a migration plan Once you know the devices that need to be replaced and the dates they need to be replaced, you’ll need to create a schedule for migrating to another solution. This may require coordinating significant updates and retrofits with your customers. Or it could be a matter of planning a transition to another service with your carriers. Your migration plan will depend on the unique circumstances of your business. 3. When does sunset occur? In fact, there is no universal date when operators will shut down their 2G and 3G networks. Each Mobile Network Operator (MNO) must decide when it makes the most sense for their business based on local demand, their goals and what they are capable of. Many carriers have already phased out 2G service and many have plans to phase out 3G by the end of 2022. You can deploy IoT anywhere in the world, here’s a complete list of 2G and 3G sunsets planned by country and provider. Africa America Asia Europe Oceania

Africa still lags behind other regions when it comes to reforming the spectrum to adapt to LTE, and there are no specific dates for 2G and 3G to be phased out. However, some countries and networks have reported that 2G or 3G service is currently unavailable.

North America, especially the US, is rapidly deploying 2G networks on a large scale. In South America, Claro has already announced future 2G and 3G shutdown dates in several countries.
East Asia leads the way in turning off 2G networks along with some other Asian countries below. Some countries in the region, such as Japan, Macau, Singapore and South Korea, do not have 2G available. In addition, many network operators have already planned future 3G shutdowns.
In some European countries and networks, it may happen when 2G can outlive 3G. For example, the Norwegian operator network Telenor announced the shutdown of 3G in 2020 – five years before 2G. Similarly, Vodafone has announced that it will phase out 3G networks in several European countries in 2021 and 2022.
With the exception of Vodafone New Zealand, most major operators have now discontinued 2G service in Australia and New Zealand. On the other hand, there are no plans for a large-scale 3G shutdown in the region.
